Pokemon Sun & Pokemon Moon Wiki Guide

SOS Battle Exclusive Pokemon (Ultra)

Pokemon Ultra Sun and Moon features the SOS Battle mechanic that allows wild Pokemon to call for an Ally Pokemon to join the battle. Each wild Pokemon has a small selection of Ally Pokemon that it can call for help, some of which will only appear in the game through this mechanic.

Some Pokemon can only be caught as Ally Pokemon through SOS Battles, while others can appear as both Ally Pokemon and through standard evolution means.
